Added changes to support Python's native iterator protocol in Stroke and StrokeVertexIterator.

freestyle_init.py
* Added a generic getName() method that allows subclasses to omit the method to return their class names.

BPy_Convert.cpp
BPy_Convert.h
* Added to BPy_StrokeVertexIterator_from_StrokeVertexIterator() a second argument to specify the direction (reversed or not) of the iterator to be created.

BPy_Stroke.cpp
* Added support for Python's native iterator protocol.
* Added code to parse the optional argument of strokeVerticesBegin().

BPy_StrokeVertexIterator.cpp
BPy_StrokeVertexIterator.h
* Added support for Python's native iterator protocol.

Stroke.cpp
* Fixed a null pointer reference.

Stroke.h
* Added new method Stroke::strokeVerticeAt(i) that returns the i-th StrokeVertex of the Stroke.
